Definitions

  • the invention relates to a height-adjustable bearing for transferring and lifting or lowering heavy loads of buildings, in particular bridge structures .
  • Height-adjustable bearings of this type consist of a container or pot made of steel with a circular or rectangular outline.
  • a cover plate, also made of steel, is partially embedded in the container or pot, through which a pressure space enclosed on all sides is formed together with the walls of the container or pot and its bottom.
  • this pressure chamber there is a plate which completely fills it and is made of an elastomer material and can deform elastically under the action of pressure.
  • This type of bearing has the property that the cover plate, on which the structure or the bridge part rests, can be shifted from the horizontal to a certain angle by tilting, because the pressure pad made of the elastomer material can be elastically compressed on one side and the cover plate is able to tilt due to the flexibility of the edge sealing elements without edge friction.
  • bearings can also be used to raise or subsequently lower a heavy load of a building or a bridge if they are equipped with a device for pressing in a pressure medium compatible with the elastomer from the outside into the pressure space enclosed on all sides.
  • a device for pressing in a pressure medium compatible with the elastomer from the outside into the pressure space enclosed on all sides.
  • the elastomer plate is displaced locally and the volume of the pressure space enclosed on all sides is increased, so that the cover plate rises with the structure resting on it.
  • the enclosed volume can be reduced again and the cover plate with the building can be lowered again.
  • Height-adjustable bearings of this type can perform several tasks. They can be used for bridges or other heavy structures where subsidence or foundation will have to be lowered over time. These reductions can be compensated for by increasing the bearing. If the subsidence becomes too large and the increase in stock is insufficient, the bearings must be removed and the contact surfaces or abutments are increased. Then height-adjustable bearings are used to raise the bridge or structure so that the previous bearings can be removed; this may also be necessary in order to inspect or replace these previous bearings. Depending on the circumstances, it may also be sufficient to install the new height-adjustable bearings and remove the old ones.
  • a pressure line opening into the pressure space below the elastomer plate is arranged in the bottom of the container or pot.
  • a plastic or elastic material can be pressed in from the outside through the pressure line, which material is evenly distributed over the bottom of the pot or container and the elastomer plate, thereby displacing this plate upwards.
  • a more or less uniform layer of the pressed material is formed. Because of the incompressibility of the elastomer, the volume of the pressure chamber increases due to the pressed-in material, the cover plate lifting up under the load of the structure lying thereon in accordance with the volume of the pressed-in liquid.
  • the disadvantage is that the spreading of the pressed material between the bottom of the container and the elastomer plate is completely uncontrolled. With a greater degree of increase, it is therefore not always possible to avoid the fact that, despite the seal, the pressure medium penetrates into the gap between the pot wall and the elastomer plate and rises and, under unfavorable circumstances, emerges from the gap and enters the outside gives way. This can be the case in particular if, in the case of a bearing that is heavily stressed by the tilting movements of the cover plate, the sealing elements have been worn out for a long time to seal the gap.
  • the warehouse is therefore unusable for lifting and lowering processes. Additional sealing problems occur at the connection of the pressure line running through the tank bottom to the bladder.
  • the flexible, elastic membrane bladder so that it consists of only one initially flat, flexible, elastic membrane plate, which is arranged concentrically on the bottom of the container and is connected to its base in a non-displaceable and liquid-tight manner.
  • the pressure medium preferably hydraulic oil
  • the membrane plate bulges upwards and also displaces the elastomer plate upwards.
  • the cover plate rises by a certain amount under load. For lowering, a quantity of pressure medium is discharged from the pressurized membrane space via the pressure line, which corresponds to the desired degree of lowering.
  • the invention relates to such a height-adjustable bearing for transferring and lifting or lowering heavy loads of structures, in particular bridge structures, which in a container or pot made of steel has a thick elastomer plate resting on the container bottom, on which one inside the container wall Height-adjustable cover plate rests, which is used for the articulated transmission of the loads on the elastomer plate to the bottom of the container, and with a circumferential sealing element for sealing the circumferential gap is provided between the cover plate and the container wall, and in the case of lifting the cover plate under the load, a locally displacing the elastomer and increasing the volume of the pressure space, consisting of the container base, the cover plate and the container wall, by means of an amount of pressure medium from the outside the bottom of the pressure pipe can be pressed in, and that a quantity of pressure medium which reduces the height of the pressure space enclosed on all sides can be discharged to lower the load.
  • the invention consists in the fact that in the resting on the container bottom, the all-round closed pressure chamber filling an elastomer plate is inserted in a parallel plane extending to the bottom of the container, the outer contour of which is at a certain distance from the container wall, and which at least one Place has an opening which is connected to the pressure line emanating from the bottom of the container for the pressure medium to be pressed.
  • a special membrane bladder made of a flexible or elastic material is no longer required, and therefore the associated or caused disturbances are eliminated.
  • a similar membrane element which is however firmly connected to the bottom of the container, is also avoided, which tends to leak and can likewise cause malfunctions. Rather, the elasticity and thus the Elasticity of the elastomer plate is used, which is designed by means of the separating disc to form a receiving space for the pressure medium to be pressed.
  • the pressure medium can be a liquid, for example hydraulic oil, or else a pasty pressure medium.
  • a plurality of openings for introducing the pressure medium into the space above the separating film can also be distributed in order to achieve a faster and more uniform distribution of the pressure medium in the cavity within the elastomer plate.
  • a further embodiment consists in the fact that each existing opening of the separating film, from which the pressure medium to be pressed in can emerge and which is connected to the pressure line, is connected to the outlet channel of an outlet nozzle, which is detachably fastened to the bottom of the container, and into a corresponding one Recess fits on the underside of the elastomer plate.
  • the separating film consisting of a plastic or metal maintains a distance of its outline from the container wall parallel to the container bottom, which is approximately 1/8 to 1/12 of the free internal dimension of the pressure chamber. This prevents overstressing in the edge area of the elastomer sheet due to an excessive notch effect due to the swelling of the material. Even if such overstressing occurs and thereby the elastomer plate locally in its edge area tearing and thereby creating an outlet for the pressure medium, damage could not occur.
  • the pressure medium emerging in the gap between the elastomer plate and the container wall would be held back by the circumferential seal. But there would also be the possibility that the pressure medium overcomes this seal and escapes to the outside. In this case, too, there is no risk of damage, as this would only cause the bearing to sink a little until the leak is closed again by pressing together. The camp would remain fully functional.
  • the separating film is provided on its outline with a circumferential ring made of metal or plastic.
  • the circumferential outer edge can furthermore be provided with an upwardly directed bead in which a circumferential metal ring is vulcanized.
  • the height-adjustable bearing is shown in the lowered state in the left half of FIG.
  • the cover plate is designated 1, the container bottom with 2 and the container wall with 3; the pressure chamber 14 is formed by these parts.
  • the elastomer plate 4 is arranged on the container bottom 2 and surrounded by the container wall 3.
  • the release film 5 is embedded, which is coated with a release agent in the manufacture of the elastomer plate 4, so that there is no connection between the elastomer material and the release film material.
  • the separating film 5 is connected to the mouthpiece 9, which is provided in the center with an injection channel 12 for the printing medium.
  • the mouthpiece 9 with the separating film 5 is detachably connected to the container base 2 by the screw fastening 11.
  • the opening in the elastomer plate 4, from which the pressure medium to be pressed emerges and the space above the elastomer plate 4 is filled, is designated by 16.
  • the increase in the bearing that occurs due to the increase in volume of the pressure chamber due to an increase in the height of the pressure chamber is 14 designated. With 15 the distance of the outline of the separating film 5 from the wall 3 of the container is marked.
  • a pressure medium is pressed in from the outside via the press-in channel 12.
  • the printing medium emerges upward from the central opening of the separating film 5 and is distributed above the separating film 5 in the resulting cavity 13 between the separating film and inside the elastomer plate 4. This causes an increase in the volume of the pressure chamber 14 and the cover plate 1 with the ballast is raised.
  • the bearing in the raised state is shown in the right half of FIG. 1.
  • the cavity 13 filled with the pressure medium in the elastomer plate 4 can be seen here.
  • a protective disk 10 is glued into the elastomer above the central recess of the separating film 5, which has the task of protecting the elastomer from erosion by the pressed-in pressure medium.
  • the separating film 5 can be made of plastic or metal.
  • a ring 6 is arranged on the periphery of the separating film 5 which is circular in this exemplary embodiment. This detail is shown in Fig. 2.
  • the ring expediently consists of the same material as the separating film. This ring 6 is intended to prevent the notch effect on the surrounding elastomer.
  • separating film 5 instead of the circumferential ring, the outer edge of the separating film 5 is provided with a bead 7 on the top, into which a circumferential ring 8 made of metal is embedded.
  • separating film 5 and bead 7 are made of plastic.
